"Salvation" is based on a rather simple concept: the starting off with a simple loop and continuously mutating it until it becomes unrecognizable. Standard stuff right? But there's more... the nd part of said mutation is then cut and looped, and mutated continuously. And so it goes through the length of this release.
Instant is well-known for epic length releases, such as the 8.5 hour "Sourcery" on Jon7.net Microlabel. This recording is not quite that long, but it is long enough to experience a thorough transformation of the source material several times over.
